Sam,

There is the alen() function for that

Returns the number of elements, rows, or columns in an array.

Syntax

ALEN(ArrayName [, nArrayAttribute])

Returns

Numeric

Arguments

ArrayName

Specifies the name of the array. If you include only the array name, ALEN( )
returns the number of elements in the array.

nArrayAttribute

Determines whether ALEN( ) returns the number of elements, rows or columns
in the array according to the following values for nArrayAttribute:

0 Returns the number of elements in the array. Omitting
nArrayAttribute is identical to specifying 0.
1 Returns the number of rows in the array.
2 Returns the number of columns in the array. If the array is a
one-dimensional array, ALEN( ) returns 0 (no columns).

The function ALEN is the answer to your question.

DIMENSION a(5)
?ALEN(a)
